CHILDS CARRIAG E.

SPECIFICATION forming part of Letters Patent No. 328,564, dated October 20, 1885.

Application filed March 6, 1885. Serial No. 157,864. (No model.)

To all whom it may concern:

Be it known that we, CHARLES F. BOST- wIoK and HORACE N. THAYER, citizens of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Childrens Carriages; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to childrens carriages; and it consists in improvements in the construction and adjustment of the springs thereof.

The invention is illustrated in the accorn panying drawing by a single figure, which is a side elevation with the Wheels removed and the rear axle in vertical section.

A marks the body; B, the running-gear frame and handles; C C, the axles, and D and E the springs on which the body is mounted.

The forward springs, E, are common C- springs, placed one on each side of the body in the ordinary manner.

It is common to mount the bodies of childrens carriages on only two springs, like E, placed as the drawing here shows them. It has also been practiced to also employ other springs at the rear end of the body-as, for example, in Letters Patent N 0. 290,704, dated December 25, 1883and an ordinary elliptical spring or springs have been used at the rear end of the body with the C-springs, like E, at the front end. The object we seek to accomplish by our construction is to provide a suitable rear spring, which shall give a neat and light appearance, and shall be contained wholly within the lines of the body, and will cause the body to maintain its horizontal position as it moves up and down, and thus avoid the objectionable tilting orpitching movement as much as possible. \Ve have found that the best spring to accomplish the above requirements is a C-springplaced with its bow in the same direction as the forward springs. The spring D, which we here show, is modified in form, so as to adapt it to use under the body,as shown. If desired, the forward springs may be made to correspond in shape with it. The exact form of this spring here shown is not essential, and may be varied in form considerably without much effect; but we consider the form shown, to be preferable. As shown, it consists of a C-formed part, d,with ends at (1 extended and curved out beyond the lines of the C-formed part d. In mounting this spring it is essential to its perfect action that at least one of its ends be attached by a pivotal connection. We prefer to connect the upper end firmly to the body, as at d, and connect the lower end pivotally to the axle C. \Ve effect this connection by an ear-clip, c, on the axle, and a bolt, 61*, which passes through the ears of the clip and an eye in the end of the spring. Ordinarily We only use one rear spring placed in the middle of the body.

What we claim as new is 1. In a childs carriage, the combination, with the body A and forward C-springs, E, of a rear spring consisting of a C-formed part, d, and extended ends (1' d, curved out beyond the C-formed part and placed with its bow in the same direction as those of the forward springs.

2. In a childs carriage, the combination, with the body A and forward C-springs, E, of the rear C-spring, D, with its bow in the same direction as those of the forward springs and one of its ends connected pivotally, substantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.
